Abstract
Cosmetic skin or hair care compositions containing a liquid, inert, hydrophobic fluorocarbon infused with carbon dioxide. The compositions increase blood flow to the skin, thus increasing endogenous oxygen and nutrient delivery to the skin.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A cosmetic skin or hair care oil-in-water emulsion comprising: i) from about 0.1% to about 70%, by weight of the emulsion of a fluorocarbon infused with carbon dioxide wherein the fluorocarbon is inert, liquid at 25° C. and hydrophobic and is selected from the group consisting of perfluorooctane, perfluorodecane, perfluorodecalin, perfluorooctylbromide, perfluorodecylbromide, perfluorooctyliodide, perfluorotripropylamine, perfluoro-tributylamine, bis-(F-butyl)-ethene and perfluoro-polymethylisopropyl ether; ii) an ingredient selected from the group consisting of a sunscreen in an amount from 0.1 to 25% by weight; and a cationic conditioning agent in an amount from 0.01 to 10% by weight; iii) a cosmetically acceptable vehicle.
2. A method of delivering endogenous oxygen to skin, the method comprising applying to skin a cosmetic skin or hair care composition comprising: i) from about 0.1% to about 70%, by weight of the composition, of a fluorocarbon infused with carbon dioxide wherein the fluorocarbon is inert, liquid at 25° C. and hydrophobic and is selected from the group consisting of perfluorooctane, perfluorodecane, perfluorodecalin, perfluorooctylbromide, perfluorodecylbromide, perfluorooctyliodide, perfluorotripropylamine, perfluoro-tributylamine, bis-(F-butyl)-ethene and perfluoro-polymethylisopropyl ether; and ii) an ingredient selected from the group consisting of a sunscreen in an amount from 0.1 to 25% by weight and a cationic conditioning agent in an amount from 0.01 to 10% by weight; and iii) a cosmetically acceptable vehicle.
3. A method of preparing the emulsion of claim 1, the method comprising infusing fluorocarbon with carbon dioxide and subsequently incorporating the fluorocarbon infused with carbon dioxide into the emulsion.Join the waitlist — get patent alerts
